Suppose a population contains 1,000,000 people, 5000 of whom have a disease. The table shows the number of people who have the disease and test positive, etc.

	Positive test	Negative test	Total
Has disease	4885	115	5000
Does not have disease	73,630	921,370	995,000
Total	78,515	921,485	1,000,000

Based on the table, what is the probability that a person who tests positive actually has the disease?
